I took my 2012 X5 to my local dealership for some A/C service, a tpms warning light service and recall work on the front axles. Upon making these repairs they also said I had an oil leak from the oil filter gasket housing which they also repaired. They test drive it and in doing so said the vehicles was running poorly and now it won't turn over at all and I need a new engine all together!! : Has anyone else experienced catastrophic engine failure like this just out of the blue?
